The United States hasn’t found proof of direct Russian government involvement in the downing of Malaysia Airlines Flight MH17 — but senior intelligence officials on Tuesday blamed Moscow for supplying the missile.

Officials said Russia “created the conditions” that led to the deadly attack by arming the Ukrainian rebels suspected of firing the SA-11 surface-to-air missile that blew the Boeing 777 out of the sky on Thursday.

One official also said the passenger plane was most likely shot down “by mistake” — killing all 298 people aboard and sparking an ongoing crisis.

The officials said they didn’t know if any Russians were present when the weapon was fired, or who pushed the button.

“We don’t know a name, we don’t know a rank and we’re not even 100 percent sure of a nationality,” one official said.

“There is not going to be a Perry Mason moment here.”

Earlier in the day, a Ukrainian official said the missile was “absolutely” fired by a Russian.

Vitaly Nayda, Ukraine’s director of informational security, told CNN that his government “taped conversations” of a Russian officer with his office in Moscow “several minutes before the missile was launched.”
